To all whom-it may concern I g Belt known that l, JosnrrrAg GANAHL, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles state of California, have invented anew and use fullVeightless VVin'dow-Sash Support; "of

. which the following is a specificatmn.

This invention relates to weightless window sash supports such as areused as attacluncnts to the sash to support it at any height to which itmay be raised in the case ment, and which operate to support the sashwithout the use of, counter-weights. The

device involves the use of a roller which is resiliently pressed againstthe window casement and this roller is moruited in a guide whichconverges toward tllQfEtLCG-Of the casement in an upward direction,Iii-raising the sash the roller rollsf'reely on the casementa but. whenthe sash is permitted todescend slightly the roller should jam on thecasement and prevent further descent of the sash. However, inldevioes orthis kind it is found that, there is difiiculty in eflectingan upwardmovement of the roller in the guide. The general object of thisinvention is to provide a, device or" this kind with improved meansforinsuring a relative, upward movement of the, roller: in the, guide whichwill insure. that the roller willpress on the face ofthe casement withsufficient force. to hold the sash in its raised position. 7

In Fig. 1 my device is illustrated in dotted lines applied to the stile2 of the lower sash 3 of a' window, the sash being mounted to slidevertically in the usual manner in a window casement 4i.

My invention may be embodle'd'in different types of sash supports; Figs.2 to-Ai illustrate the details of the type shown in Fig. 75

1, involving the use of a resilient bar or sprmg carrying two rollers,whlle Fig. 5

involving the use of a single ro11er.,;

The embodiment illustrated in Figs. "1 to- 4 mcludes a base-plate5, inthe formv of an elongated plate secured in the bottom'ofia recess 6',formed in the stile 2. Iprovide a resilient bar or springi and a,bolt'8, which may be. of carriage bolt type, whichpasses through thebase-plate andthebar and secures the same inthe stile, theouter endiofthe said bolt 8 being threaded and receiving a threaded sleeve 9; withan enlarged screwhead 10; A head upon this sleeve 9-seats against anannular washer 11 which receives illustrates an embodiment oftheinv'ention the thrust of the sleeve. when the same is.

tightened up on the threads of the bolt. This screw-head 10 is exposedon the face of the stile which receives the paneofglass 12 so that itcan be tightened up vvithout're-' moving the sash. The middle ,-portion'of the bar 7' does not rest against the'plate 5v but the bar does restagainst the'pl'ate toward" its ends forwhich purposethe base-plate 5" isprovided with abutments 13"which may be formed by bending the plateoutwardly: at its ends. These abutments operate as fulcrums for thespring bar and when" the sleeve 9 is tightened up the outer ends of thebar will be adjusted nearer to the inner face 14 of the casement alongwhich the rollers 15 run. The-serollers .15 are mounted inroller-carriers. 16 formed on, or'attached to, the ends of the bar. Eachroller has a limited vertical movement in itsgcarrier and the carrierisprowi de d with guiding means in guiding the roller toward theeasement- Ill) :with its ends projecting into the slots.

in an upward direction, in other words, the guiding means convergestoward the face 14 of the casement in an upward direction. In thepresent instanceeach roller-carrier is formed with side. plates 17 andthese side plates have aligning slots 18 which receive a pin 19 whichextends through the roller The slots in the lower roller-carrier alsoconverge toward the face 14L in an upward direction.

If desired they may be made substantially 7 parallel with the slots inthe upper rollertheroller-carr er with means tor engaging i the sideofthe roller which is opposite to the; noses 20 with the rollers, Thiswill. i noses and transfers the pins of the rollers to the casementfaceil l, and this may be in the I form; of. a projecting nose 20; inthe present instance this is in .the form of a convex plate located atthe side of the guiding. means which is opposite to the wlndo-wcasement, and, if, desired, it may be scored or formed with serrations21 on its convex face.

If desired, this'nose may be struck up from the material of theroller-carrier, see Fig. 5.

In considering the mode of operation of the device it should beunderstood that it is not the friction developed at the rollers or theirpins that directly supports the device, but it is the pressure of the.opposite stile against the face of the easement, that supports the sash.When the sash has been raised to the desired relative downward movementwith respect to the rollers, and this movement will be su'llioienttocause an engagement of the faces of cause the rollers to roll upwardlyonthe the'upper ends of the guide slots. The slots are widened out'asmay be necessary to clear the pm when the roller 1s moved laterally 1nthe slot in eitecting this upward movement.

I'Vhen the rollers are located at the upper ends of the guide slots, thepressure of the sash laterally against the casement will operate tosupport the sash in its raised position. In lowering the sash it may bepushed down by exerting suficient force, but this downward .movement ofthe sash will not cause any change in the, position of the T011: 'ers atthe upper ends of the slots. This modeot operation is illustrated in 4.

height, if it is permitted to descend slightly,the sash will have :1

Instead of embodying my invention in this bar type of sash support, Imay embody it in a type of sash support in which a single roller 22isprovided (see Fig. 5). In this case the roller-carrier 23 is in the.form of an open box with end walls 24 which are guided in a box-formedguide 25 which is countersunk in a recess 26- in the inner face 27 ofthe stile 28. The roller-carrier has side walls 29 provided with guidingmeans, such as slots 30, which converge toward the face of the windowcasement in an upward direction. In this instance the engaging means forthe face of the roller 22 which is remote from the easement is in theform of carrying the stem 32; the outer end of this stem is received inan inner sleeve 33 which is threaded in a bushing 34 set in the stile. Aspace is left between the bottom wall 35 of the carrier and the bottomwall 36 of the socket-plate or bracket 25, and in this space a coilspring 37 is provided disposed around the stem 32. 'Ihis spring exertsitsforce to shove the carrier and roller resiliently outwardly andpresses the roller 22' against the face ofthe casement. The bushing 34:is held in plape by a ferrule which screwed on 1ts ends which projectsbeyond the outer face of the stile. By applying a screw-driverin thescrew-slot 39 'at the enter a plate"31 'struckfrom the box wall, and Iend ofthe inner sleeve 33, the pressure of this spring can be adjusted,it being understood that the end of this spring thrusts against theinner end of the sleeve 33.

With this embodiment of the invention the mode of operation issubstantially the same as that described above in connection with Figs.1 to 4:. In this construction also there should be some lateral orhorizontal.

play of the roller in the guiding means. In the present instance this'isaccomplished as in the first embodiment of the invention dey scribed,bymaking the pin 40 of smaller diameter than the wide parts of the slots30.

In raising the sash the pressure of the spring is relievedjb-ecause therollers will drop down to the lower ends otf the slots, so that theonlyresistance offered is the weight of the sash. I 7

If desired the springs can be adjusted to such an extent that therollers will stay at the lower ends of the slots The sashes can then beraised or lowered by exerting more force. I i

In practice, the inner end of the stem 32 is slightly upset to form aknob 32*, and the mouth of the sleeve 33 is slightly b urred down asindicated to contract it slightly. Thls keeps the stems 32 from comingvout of the sleeves in being thrown about or handled. I

It is understood that the embodiment of the invention. described hereinis only one of the many embodiments this invention may take, and I donot sign to be limited in the;

' practice of the invention, nor in the claims,

to the particularembodiment s etforth.
